Objective To analyze and compare images of radial head fracture of 50 patients acquired by computed radiology(CR),coronal plane and axial plane of CT scan.And to determine routine plane of CT scan for radial head fracture.Methods Images of of radial head were acquired by CR,coronal plane and axial plane of CT scan on 50 patients with radial head fracture initially diagnosed by orthopedists. classify all the cases of radial head fracture into type Ⅰ、Ⅱ、Ⅲ and Ⅳ according to the classification proposed by Mason.Results The positive incidence of CT and CR were 96%(48)and 78%(39) respectively.Cases of 94%o(47)through CT coronal scan and 82%(41)eases through CT axial scan were exactly classified.Conclusion The designation of the plane of CT scan is significant to the classification of the radial head fracture.Coronal plane CT scan can meet the need of imaging clinical classification and is recommended to be routine plane of radial head fracture.In order to ensure the exact classification axial plane and 3D reconstruction technique should be added for type Ⅲ and type Ⅳ of radial head fracture.

Carotid-cavernous fistulas (CCFs) are abnormal arteriovenous anastamoses between the carotid artery and the cavernous sinus. These fistulas may be classified by cause (spontaneous or traumatic), flow velocity (high or low), or pathogenesis (direct or indirect). The most commonly adopted classification is that described by Barrow based on arterial supply. Traumatic CCFs are almost always direct shunts between the internal carotid artery (ICA) and the cavernous sinus. General features of CCFs, which may be apparent with any lesion, including bruit, headache, loss of vision, altered mental status and neurological deficits. Some fistulae may present primarily with hemorrhage before any evaluation can be performed. However, hemiparesis has been rarely observed. Only a literature review of Murata et al reported a case of hemiparesis caused by posttraumatic CCF, in which the fistula resulted in venous hypertension and subsequent brainstem congestion. While in our case, cerebral infarction was caused by total steal of the blood flow. The patient recovered after occlusion of the fistula with a detachable balloon.

3 mg/L was significantly worse than in those with hs-CRP≤3 mg/L (18.18%,5.45%;P=0.044,log-rank test). Higher hs-CRP concentration was an independent predictor of death or new vascular event(OR 3.609;95% CI 0.869—14.992;P=0.047).Conclusion Higher hs-CRP concentration in acute phase after ischemic stroke is an independent predictor of death or new vascular event in a year.

OBJECTIVETo observe different degrees of intra-abdominal pressure and different duration on the intestinal permeability and endotoxin/bacteria translocation in rabbit model, so as to explore the mechanism of the development of abdominal compartment syndrome (ACS) and MODS.

METHODSRabbit model of intra-abdominal hypertension was established by injection of gaseous nitrogen into the peritoneal cavity. Thirty-nine New Zealand white rabbits were employed in the study. The change in intestinal permeability was determined by fluorescein isothiocyanate dextran (FITC-D) and two kinds of molecular probes of type II horseradish peroxidase (HRP-II). The effects of intra-abdominal hypertension on the endotoxin/bacteria translocation were also detected.

RESULTSThe contents of FITC-D and HRP-II in portal veins increased evidently (P < 0.01) when intra-abdominal pressure (IAP) was higher than 20 mmHg. The endotoxin (ET) content in portal vein in rabbits with IAP of 10 mmHg for 1, 2 and 4 hours exhibited no difference compared with that in normal control, while the ET content increased obviously after 1 hour with IAP of 20 mmHg and increased thereafter along with the prolongation of IAP, and increase in pressure. The bacterial translocation rates were 33.3%, 66.7% and 100% when IAP was maintained at 20 mmHg for 1, 2 and 4 hours, respectively, and there was evidence of bacterial translocation to the liver. The rate of bacterial translocation to intestinal mesenteric lymph nodes was 100% when IAP was 30 mmHg for 1 and 2 hours. There was no bacterial translocation to the spleen in all experimental rabbits.

CONCLUSIONIntestinal mucosal permeability increased significantly with increased endotoxin content in portal vein when IAP was higher than 20 mmHg. At the sane time, the bacteria could be translocate to intestinal mesenteric lymph nodes and liver, which might be constitute one of the important factors leading to the development of ACS and MODS.

OBJECTIVETo evaluate the erectile and ejaculatory function of sacral tumor patients after sacral nerve root resection and investigate the relationship of erectile and ejaculatory dysfunction (EED) with the level of sacral nerve injury.

METHODSThis retrospective study included 47 male patients aged 16 to 63 (32.6 +/- 6.8) years treated by sacral tumor resection between January 2008 and August 2013. According to the levels of the sacral nerve roots spared in surgery, the patients were divided into four groups: bilateral S1-S3 (n=16), unilateral S1-S3 (n=21), unilateral S1-S2 (n=6), and unilateral S1 (n=4). The patients were followed up for 12 to 41 (27.2 +/- 10.9) months by questionnaire investigation, clinic review, and telephone calls about their erectile and ejaculatory function at 3, 6 and 12 months after surgery and in August 2013.

RESULTSIn the bilateral S1-S3 group, the incidence rates of EED were 31.25% (5/16), 25% (4/16), and 12.5% (2/16) at 3, 6, and 12 months respectively after surgery, with recovery of erectile and ejaculatory function in August 2013. The incidence rates of EED in the unilateral S1-S3 group were 85.71% (18/21), 71.43% (15/21), 52.38% (11/21), and 42.86% (9/21) at 3, 6 and 12 months and in August 2013, respectively; those in the unilateral S1-S2 group were 100% (6/6), 83.33% (5/6), 83.33% (5/6), and 66.67% (4/6) at the four time points; and those in the unilateral S1 group were all 100% (4/4). No statistically significant differences were found in the incidence rate of EED among the patients of different ages or tumor types (P > 0.05).

CONCLUSIONThe incidence of postoperative EED in male patients treated by sacral tumor resection is closely related to the mode of operation. Sparing the S3 nerve root at least unilaterally in sacral tumor resection is essential for protecting the erectile and ejaculatory function of the patient.

OBJECTIVETo investigate the protective effect of phosphodiesterase type 5 inhibitors (tadalafil) on the testis following testicular ischemia-reperfusion injury in rats.

METHODSEighty-four healthy adult male SD rats were randomly and equally divided into groups A (sham operation), B (testicular torsion + low-dose tadalafil), C (testicular torsion + high-dose tadalafil), and D (testicular torsion + placebo). Models were established in the latter three groups by 7200 torsion of the right testis for 2 hours. The animals in groups A and B were treated by gavage with tadalafil at the dose of 0. 5 mg per kg per day, those in group C at 2 mg per kg per day, and those in group D with saline at the same dose. After 3, 7, and 14 days of treatment, the torsioned testes were harvested for evaluation of the superoxide dismutase (SOD) activity and malondialdehyde (MDA) content in the testis tissue. The pathological changes in the testis were observed under the light microscope.

RESULTSAt 3, 7, and 14 days, the SOD activity was (254.46 +/- 7.43), (278.49 +/- 8.33), and (317.99 +/- 3.31) nU/mg prot in group B, and (277.12 +/- 8.80), (309.40 +/- 2.14), and (320.39 +/- 4.72) nU/mg prot in group C, all obviously higher than in D ([223.21 +/- 4.65], [231.45 +/- 4.16] and [248.28 +/- 5.74] nU/mg prot), while the MDA content was lower in the former two groups than in the latter. At 3 and 7 days, the SOD activity was significantly higher and the MDA level significantly lower in group C than in B (both P < 0.01) , while at 14 days, neither showed any remarkable differences between the two groups (P > 0.05). No obvious histopathological change was observed in the testis tissue of group A. At 3 and 7 days, pathological examination of the testis tissue revealed significant differences in the number of seminiferous epithelial layers, testicular histological score, and seminiferous tubule diameter in group B (P < 0.01), but the three indexes at 14 days in group B and at 7 days in group C exhibited no remarkable differences from those at 14 days in group A.

CONCLUSIONTadalafil can alleviate testicular ischemia-reperfusion injury following testis torsion/detorsion in a time- and dose-dependent manner.

This study was conducted to investigate the wild and cultivated resource situation of Rheum tanguticum in main production area of China, estimate its reserves, and put forward the feasible approach for the sustainable utilization of R. tanguticum. On the basis of the literature data about R. tanguticum, conbined with interview, investigation and sampling investigation, the total reserve of resources is estimated using the route-quadrat method and the vegetation and soil-type map area method proposed by our research group. The results indicate that there is no obvious change between the present distribution ranges of the wild R. tanguticum and its historical records, but its population density has changed clearly. The reserve of the wild R. tanguticum has seriously declined in lots of place, even faced the exhaustion in some regions. According to the investigation, the resource reserve of the wild R. tanguticum is no more than 5 000 t, and the cultivated is about 1 607 t. The resource reserve of the wild R. tanguticum is nearly depleted, and this suggests that the wild R. tanguticum should be enrolled in the protection plant list, and the cultivated will become the main resource of Rhubarb in the future. So it is extremely neccessary to collect and protect the germplasm resource of R. tanguticum, establish the germplasm nursery and repository, and conduct breeding research on those bases.

Curcumin has been reported to possess antitumor activity with low toxicity. However, the clinical application of curcumin has been significantly limited by its instability and poor metabolic property. In order to overcome these limitations and discover novel small molecules with potential antitumor activity, 29 curcumin mimics were synthesized, which were confirmed by 1H NMR and HR-MS, and their cytotoxic property was evaluated against five human cancer cell lines in vitro. Compounds 16, 18 and 19 exhibited good cytotoxic property, their IC50 value were even below 5 micromol x L(-1) to some cancer cell lines, 5-9 times better than curcumin.
